BOOST METRIC BASED PRE-EQ LIMITING SYSTEMS AND METHODS

Boost is provided. A circuit of a cable modem can be configured to receive, at a first input, a first message from a device over a channel, the channel comprising various subcarriers. The circuit can determine a transfer function associated with each of the subcarriers, the transfer function including an indication of power transfer between the circuit and the device. The circuit can determine, using the transfer functions, a power adjustments corresponding to the subcarriers. The circuit can determine, using the power adjustments, another power adjustment for the channel. The circuit can transmit, at a first output, a second message over the channel, the transmit power of the second message responsive to each of the power adjustments.
